I forgot to add that 2400 to 2450 is being taken away more and more, we
for exsample are only allowed to use it for satalite communication
making using modified wifigear for that band useless for us.

Lucky hamradio and amrp is not limited to the USA so most of us do not
have to worry about the USA limitations.
In region 1 we got between 6 and 10 Mhz and usualy only 1 Mhz is in
active use leaving plenty of room for high speed data modes especialy
if FHSS is used.
